Astronomers using the National Science Foundation’s Very Large Array radio telescope have found previously unseen evidence that galaxy collisions trigger energetic quasar activity in relatively nearby galaxies.
Scientists and engineers at the National Radio Astronomy Observatory (NRAO) have made a giant leap toward the future of radio astronomy by successfully utilizing the Very Large Array (VLA) radio telescope in conjunction with an antenna of the continent-wide Very Long Baseline Array (VLBA) using the longest fiber-optic data link ever demonstrated in radio astronomy.
For the first time, astronomers have determined the intrinsic size and shape of the highly charged region of radio emission surrounding what most scientists believe to be a supermassive black hole at the center of our own Milky Way Galaxy.
The smallest protoplanetary disk ever seen rotating around a young star has been detected by an international team of astronomers using the National Science Foundation’s Very Large Array radio telescope.
Astronomers have found evidence for the most powerful magnetic field ever seen in the universe. They found it by observing a long-sought, short-lived afterglow of subatomic particles ejected from a magnetar — a neutron star with a magnetic field billions of times stronger than any on Earth and 100 times stronger than any other previously known in the Universe.
Planets apparently can form in many more binary-star systems than previously thought, according to astronomers who used the National Science Foundation’s Very Large Array radio telescope to image protoplanetary disks around a close pair of stars.
Radio telescope studies of the fiery afterglow of a Gamma Ray Burst have provided astronomers with the best clues yet about the origins of these tremendous cosmic cataclysms since their discovery more than 30 years ago.
A team of astronomers says that observations with the National Science Foundation’s Very Large Array radio telescope show that a neighboring bloated star has giant convective plumes propelling gas from its surface up into the star’s atmosphere.
A team of astronomers using a pair of National Science Foundation radio telescopes has made the first measurements of the size and expansion of a mysterious, intense fireball resulting from a cosmic gamma ray burst last May.
Marking an important new milestone in radio astronomy history, scientists at the National Radio Astronomy Observatory in Socorro, New Mexico, have made the first images using a radio telescope antenna in space.
